The long-standing rumour is that McCartney and Ono did not meet eye to eye, and that she was in part responsible for breaking up The Beatles.

However, McCartney told Stern he felt she had been a good partner for John Lennon.

“Even though we thought she was intrusive because she used to sit in on the recording sessions and we’d never had anything like that. But looking back on it, you think, ‘The guy was totally in love with her. And you’ve just got to respect that.’ So we did. And I do,” he said.
